Now I have the CLASS CPUFeatures working nicely well with x86 64-bits.

Cleaned up te data to outside of the code segment.

Some work with the register's usage with call convention for the VECTORCALL/SYSTEMV and CLASS proc member, sometimes getting really confused how to push/pop properly the register's. Research.

Indeed the MACROS are our best friend, a-lot of programming task's simplified with predef MACROS.

My wich, it's the UASM CLASS future working with x86 32-bits registers and fastcall convention. 32-bit it's coming to an end, but some old/or VIA hardware or CLOUD/virtual environment still exist with x86 32-bits.

Now it's time to start to work in uasmlib for SSE and AVX features, bringing the slow CPP code to the fast ASM code.
